Hi David, I'm looking at your Pop3 Client tool for Zope and have hit a snag. Is there any documentation about correct usage, or example (Zope) code? I'm using Zope 2.2.1 on Redhat Linux, with PopMailBase .0.0.3, and PopMail .0.0.2 I have looked over POP.py, and have a glimmer of what to do to call these methods and functions. I have added a Pop Client Folder, and a client account object, but when I try to use the "View" tab in the Zope TTW GUI, I get the tracebacks, below. The 'error_proto' is a reference to the first class listed in poplib.py, which simply 'pass(es)' when an Exception is used as a parameter. One thing I noticed is that poplib seems to treat error_proto as a function sometimes, which strikes me as odd. Some Pythonic stuff boggles my mind. Now you know as much (hopefully much more!) than I do. Thanks for any help!
